For some reason, NIL atoms are marshalled as atoms with a zero-length print name, unmarshalled without test. That's bogus. Should test NIL and not do MakeAtom on unmarshalling side. I think I'll fix it and release a version of RPCRuntime for me again, rather than trying to deal with all the non-NIL's. This will (eventually?) require a change to Lupine so that those who chose not to call the fixed routines won't get screwn.

I'm no longer convinced that queueing is needed in the Smarts at all. Probably one for the Lark keyboard, just to keep the characters flowing, but otherwise, now that conversation state is reported back for each call, it may not be necessary. Seems artificial every time I queue something. WaitForActive also has to do something like that, but a simple condition variable thing might well be good enough there; Progress is reported in its own process.
December 18, 1985 11:52:01 am PST
During connect attempt, if get "initiating" in but "notified" fails, should enter error state or something — all smarts.
December 18, 1985 11:52:35 am PST
Think about whether a common set of smarts implementations at some level would make sense.

Extensions handled wrong. Calling by number won't reach poacher as it stands. Once it does, the exotic (Finch but no Lark) stuff will get into a loop. Fix: $Extension[rName]=$number. Have a version of GetPartyFromNumber that will not follow the extension to an active party. Redefine the trunkOK bool to be trunkRequired.
November 26, 1985 4:09:21 pm PST
Call to self if poaching on somebody else reaches own office. Solution to this has to wait. Would be nice to nip all narcissism in the bud at GetParty time, but so far that's complicated. Wait.
December 11, 1985 3:21:51 pm PST
See Poachers message sent to VoiceProject^ this day to get the latest version of the switching design.

When somebody is running Finch but not an Etherphone, or doesn't have an Etherphone, another Etherphone caller should be able to call him or her, notifying the Finch of what's happening (almost -- it will look active while it's ringing) but using the back door. The easiest way is to set things up so that the callee is poaching on the caller's selected outgoing trunk. (Be careful about other calls arriving at that Finch while the first is in progress, but) Maybe the easiest way to do this is to have poaching be set up at GetParty time, computed anew, rather than at Create/Register time. Similarly, visiting, if that is retained as is. I'm going to attempt that. Poaching will be set up as a trunk is reserved for a calling party. You can do it only if the reservation succeeds. It shouldn't be changed if the present poachee is active (to prevent taking a connection away from somebody who already has it.) This sounds dangerous.

Holes in the present implementation:
Registration/Deregistration/Multiple services don't work right. Want trunk registration to be more independent. Now is the time to get registration/deregistration to work right.
Local trunk when remote not available: not sure it's implemented, probably doesn't work.
$Poaching not tested.
November 26, 1985 4:09:21 pm PST
Bug: Unsnarled a monitor lock when locked registering routine reported something via TU which uses DescribeParty which is locked, too. Unsnarl Deregistering stuff of a similar ilk. Why is DescribeParty locked anyhow?
November 26, 1985 4:09:21 pm PST
Throughout, must deal with trunks when front doors die and v/v. Or must we? Work briefly on decoupling them as much as possible, including in LarkOut.
November 26, 1985 4:09:21 pm PST
Bug: LarkSmartsImpl.DeregisterIfRegistered doesn't compute the right host atom. In fact, it needs to try various types out to be sure usages are not changing and screwing things up. As usual, the need for trunk and lark smarts to be in synch causes problems. Think the registration/deregistration/crash scene out again after things work. For now, presume that the types remain the same and that we're not registering multipled services.
November 26, 1985 4:09:21 pm PST
Don't take structures apart until all conversation-ending has been done? No need to delete parties if they can be revived.
November 26, 1985 4:09:21 pm PST
Do better job of idle party registering-deregistering-obtaining-deregistering when done.
November 26, 1985 4:09:21 pm PST
If called-party is running Finch but has no Etherphone, call via back door.
November 26, 1985 4:09:21 pm PST
Consider ways to deal with back door incoming calls while front-door busy. Every new ring now generates a new off-hook. If the callee hangs up, there might be time.

Progress report that doesn't encounter voice terminal needs to report to own trunk party, if there is one -- how?
November 26, 1985 4:09:21 pm PST
How to deal with showstopper:
When finch smarts/party dies, zap smarts, but leave party and attached conversations and poachees.
When conv is dissolved, for each party, if it's got no smarts and no other convs, zap it.
November 26, 1985 4:09:21 pm PST
Figure out what party.numEnabled means now. Finch should maybe enable its party instantly? Maybe this should apply only to voice terminal smarts? Examine how used and come to terms with it. With multiple parties involved for one participant, so to speak, numEnabled is probably not a reasonable thing to look at anyhow.
November 26, 1985 4:09:21 pm PST
$poaching/$visiting chain must be followed backwards to zap when dying (see showstopper tho.)
November 26, 1985 4:09:21 pm PST
When dealing with showstopper, fix up cfRef stuff in places like IdleConversationsForParty in ThPartyInitImpl.

November 26, 1985 4:09:21 pm PST
P: showstopper: when poacher smarts/party dies, how to represent it to conversation and other parties for duration of call; how to shut down when safe? Have to give up on finding out about calls in progress.

December 4, 1985 8:57:19 am PST
Larks register as individuals instead of telephones. TUImpl still doesn't know about trunk parties, smarts, or smartsInfo. Fixed, but DoDescribeParty has a type bug.
Conferencing is not supported at low levels. Code is in such that if 3 or more parties show up at the conversation level, conferences will be built as they go active. If a third joins a first two, the conversation should switch from conference to regular, and vice versa.
Trunks completely unimplemented.

CheckIdle is now always queued on info.reports. It waits for n seconds and then kills an old conversation. During that time no further reports can be made. It's safe to FORK a process to kill the conversation after the n second wait. That will happen asynchronously with reports about other conversations. Argle.
November 30, 1985 4:43:48 pm PST
November 30, 1985 4:59:25 pm PST
info.haveKeys is bogus. Esp. when we begin alternating among conversations. Needs to be cDesc.keyTable and larkInfo.keyTable, and we need to send one whenever they differ. Also, active isn't working at all right. The test for same-hostness now must be made by comparing send and listen socket id's.

When one goes $idle, others may go $idle, too. Or into random other states. One must be willing to accommodate those reports, rather than complaining about impossible transitions. One needn't do anything in particular about them, though. This needs fixing quite soon. Worry only about the reportToAll states. Fix: when in $neverWas state, many transitions by others are no-ops.

Ring tune cache tests assume that, on Growler at least, NamesGV.GVGetAttribute is directly bound to the impl, not via RPC. Otherwise, have to do a rope compare for equality, not just a REF compare on the ropes. See LarkSmartsSupImpl.GetringTune. Turns out to work as expected. Also determine why we didn't even try to get a ring tune for Strowger (was a collection of trivial things).

EnterLarkState[idle] clears dial tone but doesn't clear the LED -- or it comes back on or something. Doesn't really seem to be going idle. InterpretHookState is switching from sPkr to std, moving tones to handset, just before going idle, in the case of onhook. Possibly could eliminate that transition, saving some time. The real bug is that the [hookswitch, disabled] event is not being interpreted right in the Lark parser. This EnterLarkState in InterpretHookState may be responsible for the blurp when you hang up sometimes that has plagued this system from day one. Also entering reserved=>parsing for no reason, but still shouldn't explain unwillingness to go idle. Main problem was that when conversations went idle, smartsInfo.currentConvID was being zeroed before a test for relevance that protected EnterLarkState from being called at the wrong time, in LarkSmartsSupImpl.NoteNewState. Saving the previous value and using that in the test fixes it. The other problems (spurious state transitions) should be eliminated, though. Recap — This is three problems: InterpretHookState is switching to handset mode when detecting the onhook; this is spurious (and ancient); solution is to do nothing on onhook. Parser is switching to Parsing mode when detecting the onhook; this is spurious, too, and might have an analog in the past; solution is to do nothing in that case. CheckIdle is waiting in-line, since it was originally designed to be called from an MBQueued routine. Solution: change Report to have FinishProc return both the report proc and what to report. Finish proc can return something that just checks idle, instead of full progress report, when it's the initiator.
November 27, 1985 2:33:57 pm PST
November 27, 1985 2:50:29 pm PST
info.currentConvID isn't set up when conversation is initiated from LarkSmarts. ThParty checks for all idle doesn't work when there is no associated posting (need to check at end of posting for all idle and no reports outstanding.)
